Fields
Modifier and Type	Field and Description
`static RetryPolicy`	`DEFAULT` SDK default retry policy.
`static RetryPolicy.BackoffStrategy`	`DEFAULT_BACKOFF_STRATEGY` The SDK default back-off strategy, which increases exponentially up to a max amount of delay.

`static int`	`DEFAULT_MAX_ERROR_RETRY_STANDARD_MODE` SDK default max retry count for standard retry mode
`static RetryPolicy.RetryCondition`	`DEFAULT_RETRY_CONDITION` The SDK default retry condition, which checks for various conditions in the following order: Never retry on requests with non-repeatable content; Retry on client exceptions caused by IOException; Retry on service exceptions that are either 500 internal server errors, 503 service unavailable errors, service throttling errors or clock skew errors.
`static RetryPolicy`	`DYNAMODB_DEFAULT` Default policy for DynamoDB client
`static RetryPolicy.BackoffStrategy`	`DYNAMODB_DEFAULT_BACKOFF_STRATEGY` The default back-off strategy for DynamoDB client, which increases exponentially up to a max amount of delay.
`static int`	`DYNAMODB_DEFAULT_MAX_ERROR_RETRY` Standard max retry count for DynamoDB client for DynamoDB client
`static RetryPolicy`	`NO_RETRY_POLICY` No retry policy

- Field Detail
  - NO_RETRY_POLICY
```
public static final RetryPolicy NO_RETRY_POLICY
```
    No retry policy
  - DEFAULT_MAX_ERROR_RETRY
```
public static final int DEFAULT_MAX_ERROR_RETRY
```
    SDK default max retry count for legacy retry mode
    
    See Also:
    
    Constant Field Values
  - DEFAULT_MAX_ERROR_RETRY_STANDARD_MODE
```
public static final int DEFAULT_MAX_ERROR_RETRY_STANDARD_MODE
```
    SDK default max retry count for standard retry mode
    
    See Also:
    
    Constant Field Values
  - DEFAULT
```
public static final RetryPolicy DEFAULT
```
    SDK default retry policy. Amazon DynamoDB has a custom retry policy that is used when no ClientConfiguration is provided.
  - DYNAMODB_DEFAULT_MAX_ERROR_RETRY
```
public static final int DYNAMODB_DEFAULT_MAX_ERROR_RETRY
```
    Standard max retry count for DynamoDB client for DynamoDB client
    
    See Also:
    
    Constant Field Values
  - DYNAMODB_DEFAULT
```
public static final RetryPolicy DYNAMODB_DEFAULT
```
    Default policy for DynamoDB client
  - DEFAULT_RETRY_CONDITION
```
public static final RetryPolicy.RetryCondition DEFAULT_RETRY_CONDITION
```
    The SDK default retry condition, which checks for various conditions in the following order:
    - Never retry on requests with non-repeatable content;
    - Retry on client exceptions caused by IOException;
    - Retry on service exceptions that are either 500 internal server errors, 503 service unavailable errors, service throttling errors or clock skew errors.
  - DEFAULT_BACKOFF_STRATEGY
```
public static final RetryPolicy.BackoffStrategy DEFAULT_BACKOFF_STRATEGY
```
    The SDK default back-off strategy, which increases exponentially up to a max amount of delay. It also applies a larger scale factor upon service throttling exception.
  - DEFAULT_BACKOFF_STRATEGY_V2
```
public static final V2CompatibleBackoffStrategy DEFAULT_BACKOFF_STRATEGY_V2
```
    The SDK default back-off strategy, which increases exponentially up to a max amount of delay. It also applies a larger scale factor upon service throttling exception.
  - DYNAMODB_DEFAULT_BACKOFF_STRATEGY
```
public static final RetryPolicy.BackoffStrategy DYNAMODB_DEFAULT_BACKOFF_STRATEGY
```
    The default back-off strategy for DynamoDB client, which increases exponentially up to a max amount of delay. Compared to the SDK default back-off strategy, it applies a smaller scale factor.

  - getDefaultBackoffStrategy
```
public static RetryPolicy.BackoffStrategy getDefaultBackoffStrategy(RetryMode retryMode)
```
  - getDefaultRetryPolicy
```
public static RetryPolicy getDefaultRetryPolicy()
```
    Returns the SDK default retry policy. This policy will honor the maxErrorRetry set in ClientConfiguration.
    
    See Also:
    
    ClientConfiguration.setMaxErrorRetry(int)
  - getDynamoDBDefaultRetryPolicy
```
public static RetryPolicy getDynamoDBDefaultRetryPolicy()
```
    Returns the default retry policy for DynamoDB client. This policy will honor the maxErrorRetry set in ClientConfiguration. For DynamoDB the Default max error retry attempts is kept same as Standard Max retry of Dynamo DB. Thus honorDefaultMaxErrorRetryInRetryMode is set to False so that it uses max error retries same as DYNAMODB_STANDARD_DEFAULT_MAX_ERROR_RETRY which is 10.
    
    See Also:
    
    ClientConfiguration.setMaxErrorRetry(int)
  - getDefaultRetryPolicyWithCustomMaxRetries
```
public static RetryPolicy getDefaultRetryPolicyWithCustomMaxRetries(int maxErrorRetry)
```
    Returns the SDK default retry policy with the specified max retry count.
  - getDynamoDBDefaultRetryPolicyWithCustomMaxRetries
```
public static RetryPolicy getDynamoDBDefaultRetryPolicyWithCustomMaxRetries(int maxErrorRetry)
```
    Returns the default retry policy for DynamoDB client with the specified max retry count.
